Application filed November 23, 1910. Serial No. 593,886.

Z'o au -w/ioniit muy concer/i Be it known that I, HYMAN ELI GOLDBERG,

`a citizen of the United States, residing at My invention relates to controllers operating in part, at least, electrically, and the object of the invention is to provide apparatus such that the movement ot' the controlled vbody may be controlled through the medium ot' conducting ink drawn or impressed upon a non-conducting body such, tor example, as a. sheet of paper.

My invention may be applied to ,many kinds oi' machines, for instance, copyinflf,l

tvi'iesetting, sorting machines, etc.

ln order to illustrate the invention I have chosen to describe it as embodied in a copying machine adapted to print upon a receiving sheet numerals corresponding to characters which have been previously drawn yor imprinted upon a. transmitting sheet.

.in the mechanism selected and shown in.

the accompanying drawings, Figure l shows the basis of a numerical scheme by means ofwhich the `numerical digits are represented, Fig. '2 shows the method of representingvthe digits l, 2, 3,--l, 5, .6, 7, S, 9, the same'being a combination oi the character elements shown in higfl. -Figs. 3 and i are front and end elevations respectively of the contactiir which forms the traiismitting mechanism. i Fig. 5 is a plan section taken Fig. (i is'a plan section oi thcA receiving mechanism taken on the line G-G Fig. T.. Fig. 7 is a view partly mechanical andpartly diagrammatic showing the receiving mechanism and the wiring diagram thereof. The mechani al portion is a plan section taken on the line 7-7 Fig. G.`. FieS is a fragmentary section of the movable switch element taken on the line 8-8 F ig. 7. Figs. 9, l0 and 1l show modifications of the apiiaiatiis for 'using the Arabic numerals as the transmitting characters. l i

Similar numerals refer to similar pai-ls throughout the several views.

The form of the transmitting characters may be varied, but to facilitate explanation the simpler ones shown in Figs. 1 and 2, 4and Aruled Awith faint horizontal and the apparatus operating in connection therewith, will first be described.

lF r the purpose ot' permitting accurate and easier writing of. the `fi i[iiri-\.s the transmitting sheet, as for instance, a ledger sheet. isindicated in Figs. 1 and l as having been *vertical lines. The basic characters assumed' c onsists ofri'idii all diveiging in di ii'erentr directions. Fig. l shows the characters l, 2, l

and 8 which are all inclined vat. l5 and radiate from al common center which is always at the intersection*otl the, .vertical and inid- -dle horizontal line; 'lhese characters l. 2,

and S are combined as shown in liig. 2 to produce the digits l, 2 3, l. fi, o, T,- S; li. 3 equa-ls 2 plus 1; 5 equals l` plus l; (i equals i plus 2; 'i' equals l phis'plus l; Si equals S plus '1. The transmitting cliaraciers are ordinarily written by haiid with au ordinary pen, usingyelectrically conductive. ink such for example, as the ink which forms a basis t'or my copending application filed October 28, 1910, Serial No."589 ,56 5.

p Figs. f3, 'and show the transmitting mechanism or contacter which isv applied to the ink written charactersand contains terminals electrically connected to conductors formingpart of the circuits oi thc apparatus. Electric connection is established betweenV these terminals by .means of the ink which forms the transmitting characters,

the inkvthus constitutinga switch which connects various of the terminals with cach other. The contactor here shown has six groups of five terminals, one group l`or each decimal place in a six ligure number. lhicli group is made up of a central terminal 21. and tour corner terminals 20, i'i'rraiigcd at the corners of an imaginary square about said central terminal. In apphJiiig the coutactor tothe paper ruled and writtciivupoii as shown in Figs. l and 2, the terminals :2l should be placed above the common center oi the character, and the terminals 20 above the four corners. Upon pressing the plunger handlcBO, springs 31 are compressed thus dcpressing'the terminals against the force ot the lighter springs 32. Said terminals are therefore pressed into contact with the iiik written character. thus establishingr couiicctions between the various terminals 20 and the terminal ".21 in case any ink written character is present to make such connecy be engaged by the contact 62 when the plate y 41, to which it is fastened, is depressed.y rthel esta.

tions, and leaving the circuit open if no ink line joins the terminal 20 and its terminal 21. Terminal 21 is at one end of the conductor r which forms a common return for the four parallel branch conductors 1, 2, 4

and 8 which end at the terminal 20. rlhis isl illustrated diagrammatically in lfig. 7 Un the lower end of handle 30, heretofore re- `ferred to, is a plunger 34 slidable in collar supported by the top yoke 36 extending etween end frames 37. @n the lower end of plunger 34 is a horizontal plate 40 and cover 41. Below this plate, and at a distance therefrom, is a block 42 'secured by screws 43 to the end frame 37. il the terminals 20 and 21 are on the ends ofy small plungers 45 vertically slidable within the block 42, as shown at the left of lfig. rlFhe enlarged head 46 of each plunger 45 is movable vertically within chamber 47 in bloick 42. The light springs 32, are located in the bottom of each chamber 47, bearing against the bottom of the chamber and the under side of head 46, thus serving to keep plun gers 45 and consequently terminals 20 and 21 clear of the paper. Jlbove each and within the same chamber 47 is a stronger spring 31, bearing at its upper end upon the under side of piston 50,-secured, as shown at 51, into plate 40, movable with plunger 34 and head 30. @n the outside of the contactor are a plurality of small electric cables 53, each of which contains live strands of wire 54, one of these small cables 53 being intended for and connected to each group of tive terminals 20 and 21, heretofore described. rlhe wires 54 for each one of these groups pass into the sides of block 42 through holes 55 providedfor the purpose and constantly contact with the adjacent plunger 45 so that electricity entering any of the terminals 20 and 21 passes up through its plunger and thence out through its parf ticular wire 54 into its particular cable 53.

All the cables 53 illustrated in Fig. 5 areV grouped in a common cable 57 attached for convenience by means of the clamp 58 on the side of the device.l All of thewires 54 heretofore described are insulated from each other and the cables 53 are also insulated from each other as clearly appears in Fig. 5. 1n a circuit separate from the ones heretofore mentioned is a solenoid A61 which is connected by means of wires 64 to two contacts and 62. Contact 60 is fastened to the stationary block 42 and is in position to connection between the contacts 60 and 62 and their wires 64 -is made preferably 'by means of the binding posts 63. The parts are so proportioned that the contacts 60 and 62 will not come into engagement and close the circuit through solenoid 61 until after the terminals 20 and 21 have reached '96 and at the other en ministthe surface of the paper upon which the ink switch is drawn or printed. ln each circuit there is a suitable source of electric motive force such as the batteries 65 shown in Fig. 7.

l will now describe the receiving mechanism which prints the numerals or other characters to be copied. rlhe wires 1, 2, 4 and 8 are connected to brushes 71, 72, 74 and 78l respectively, which are mounted in any suitable insulating support 79, see .l*`igs.-6 and 7. 'lhese brushes engage contacts 81, 82, Sl and 3S respectively, forming part o'f the rotary disk 89 which constitutes a movable switch element. rlFhis disk is made of conductive material and the contacts are inte` gral with it and penetrate the insulation 90 fastened to the face of the disk as shown in detail in Fig. 8.` The return vwire r is con nected to a brush 91 which makes sliding contact with the back of disk 89. ln the present machine there are four of these rotary switch elements shown, although the number will vary with the capacity of the machine. The receiving mechanism shown has a capacity of four places, while the contactor has a capacity of six places', two of which will remain idle with a receiving mechanism of the capacity shown.

1t will be understood that the wiring above described and illustrated in Fig. 7 is duplicated for each place .in the capacity of the machine, except the wiring connected to solenoid ,61 which is common to the entire machine.

lilach rotary switch element is independently rotatable, being supported by spokes 92 upon shaft 93. Each disk is constantly urged in a forward direction by means of a tension spring 94 attached at one end to a lug 95 and at the other end to the casing 96. Shaft 93 is supported. in two side plates 97 which form a rocking frame pivoted upon the shaft 98 supported in the casing 96. Each rotary switch element is provided with a ratchet 100 adapted to be engaged by a pawl 101 adapted to prevent the forward rotation of said disk. Said pawls are pivotally supported upon a shaft 102 carried by the side plates 97 and are provided with arms 103 connected by means of links 104 to arms 105 which form armatures coperatin with the magnets 1'06. Tension springs l0 arey fastened at one end to the stationary bar 108 sup orted in the casing s to the eyies 109 integral with the links 104. The parts are so constructed and arranged that said springs normally urge the armatures away from the magnets and the pawls 101 into engagement with their coperating i--ttchets 100. r1`he armatures inthe present case Iare four in number, one Ifor each place in the capacity of the machine, and these armatures are independently mounted upon the shaft rigidly supported in walls 111v and 112 which form part of the stationary casing. Each magnet 1s 1n series with the return wire r and will therefore be energized when' Ithere is current in any 011e of the tour wires 1, 2, Ll, and 8. Solenoid 61 is supported at one end by the cross wall 112 before mentioned and is adapted to attract its core 120 against the force of the spring 121v contained within said solenoid. Core 120 is articulately connected by means of a cross plate 122 to two rack bars 123 provided at their forward ends with teeth adapted to engage theI pinions 124. Said pinions are integral with the keeper 125 which is mounted so as to rotate upon shaft 93 and engage the spokes 02 and hold the latter in engagement with the stationary stop bar 120. T his is the initial position of the parts, wherein they are normally kept by reason of the iact that spring- 121 is strong enough to overcome the force oi the springs 94.

The operation of the parts heretofore de` scribed is as follows: The depression of the plunger 30 of the contactor causes the termina s 20 and 21 to be connected by the ink. switch formed bythe figures or characters upon the transmitting sheet. Should there be no ink character present under any particular set of terminals 20 and 21, then there will be no connection formed between said terminals; but if there arc ink` characters present, some of said terminals 20 will be electrically connected with their associated terminal 21 and the particuli-rr magnet 10G in series with that particular' terminal 21 will be energized by Ymeans of its wire 'l' and thus attract itsarmature 105 against the Jforce of its spring 107, and withdrawing the pawl 101 from its ratchet 100, thus releasing the rotary switch element 89, 90. The further continued depression of plunger 30 now causes the contact 62 to engage the contact which immediately energizes the solenoid 01, attracting the core 120 against the force of the spring 121 and moving the connected racks 123, thus rotating the pinions 121 vand .the keeper 125. Such ot the switch elements 89, 90 as have been released by their coperating pawl 101 will now move forward under the force of the springs 94. 'The various brushes 71, 72, 74 and 78 will thus engage and make and break Contact with their coperating sets of contacts 81, 82, 84 and"89 respectively. This will continue until lthe disk 89, SPO has moved, under the force of its spring, :far enough to completely leave the contacts and rparticular form illustrated,

thus completely denergize the electric circuit therewith connected, whereupon the cooperating magnet 106 will immediately rej lease its coperating armature 105, and the pawl 101 will be brought by spring 107 to engage `the ratchet 100 at the particular tooth beneath it. The disk 89, 90 will thus have moved a number of steps dependent upon and equal to the numerical value of the ink character engaged by the terminals 20 and 21, as will now be explained in detail.

Contacts 81, 82, 84 and 88 are of dierent lengths and are arranged according to a y definite plan upon the rotary switchelement Si), 90. There are eight contacts in the set 81, four contacts in the set 82, two contacts in the set 84, while there is only one lContact S8. The contacts forming the set 81 are each l one angular step in length and one angular step apart. Contacts 82 are each two angular steps in length and two angular' steps apart. Contacts 84 are each four angular steps in length and four angular steps apart, while contact 88 is eight angular steps in length. 1t will thus be seen that a ditiierent combination of contacts will be freed and connection with them broken at each angnlar step of the disk, S9, 00. rlhus in the l i normal position represented in Fig. 7 brushes 71, 72, 74C and 78 are in engagement with contacts 81, 82, Si and 88 respectively. Should the disk now move forward one angular step, the brushes 72, 7l and 78 will still remain in engagement with their contacts, but the Contact with brush 7l will be broken. ln a similar manner at theend of the second step contact will be broken with brush 71. At the end of the third step with brushes 71 and 72. At the end of the 'fourth step with brush 74. Agt-the end of the fifth step with brushes 74 and 71. sixth step with brushes 74 and 72. At the end of the seventh step with brushes 71, 72 and 74. At the end of the eighth step with brush 78. At the end ot' the ninth step with brushes 71 and 78. At the end of the tenth step with brushes 72 and 7 S. At the end of the eleventh step with brushes 71, 72 and 78. At the end of the twelfth step with brushes 74 and 7 8. At the end of the thirteenth step with brushes 71', 74 and 78. At the end of the fourteenth step with brushes 72, 74 and 78. At the end of the fifteenth step, which is the last stepwithin the capacity of this contact will be brokenwith brushes 71, 72, 74 and 78. lt

At the end of the lla) will thus be noticed that contact is broken i with the diilierent combinations of brushes lat each differential step ofthe disk or movable switch elcnient. Now considering that connection is broken witha. different combination of brushes at each diil'erential step of the rotary switch element, and considering that at the other ends of therespective conductors the terminals 20 and 21 are joined by a selective inlr switch, it will be seen that only certain of said brushes are in circuit relation, namely only those which connect their particular terminals 20 With the common return21 by means ot the inl'r switch. Suppose the ink sivitch contacted by the terminals 20 and 21 is the numerical number 7. rllhis will establish the connec 'ion betweenl the common return r and the brushes 71, 72, and 711, the brush 80 not being` connected and therefore not entering into the circuit. Now by examining the ditiierent combinations of brushes whereby contact was broken at each vdifferential step, it will be seen that the first time when contact was broken Was when all olf brushes 1, 2 and -1 were at the end of the seventh dill'erential step. rlllhen and only then docs the magnet 100 become demagne` tized, releasing its paWl to arrest the movable switch element.V v

' l have now explained how, by Writing or printing any character on the transmitting sheet, and pressing the handle of the contactor, a differential motion will be imparted to the rotary switchl elements corresponding to the value oit the numerical character thus Written or printed. ll Will noW describe .means whereby the rotary switch elements are made to printr the corresponding numeral figures upon the receiving sheet 130 shown in Fig. 7. Numeral type 131 are formed upon the periphery of each ot the rotary switch elements, these forming the series of digits 0, 1, 2,3, 4, 5, 6, 7, 8, 0. r)The 0 is located at printing position when the parts are in the initial position shown in Fig.

rocking frame are normally held in elevated position against the stationary'stop bar 132 by the springs 133. Said side plates have an integral standing arm 131i carrying an adjust- VVable strike screw 135 in position to be engaged by the cross bar 122 secured to core 120. The arrangement is such that screw 135 will not be reached b v bar 122 until the latter has traveled some distance, to Wita distance suiiicient for the differential movement previously vdescribed to have completely takenl place.' lt is possible to depend tor the necessary slowness of action upon the natural inertia ofthe parts, although nn ordinary dash pot may be used to produce a retarding eliect it desirable. As soon as bar 122comes into Contact with screw' 135 it commences to rotate Varm 134 in a direction to lower the rocking frame and cause the rotary switch elements carried thereby to produce an impression upon the receiving sheet.

l will novv describe Vthe apparatus adapted to operate in connection with Arabic numerals instead ot the symbols above described and shown in Figs.` 1 and 2. The appearance ot the numerals is shown in Fig. 9,.as also 7. rlhe side plates 97 which form the ni i12/,aal-

are shovvn the points Where the terminals ot the contactor Will make contact with the transmitting sheet. lin this case the an rangement of the terminals is mcdihed as shown in detail in Fig. 10.. rlhe terminal 204C is connected to conductor Ll; terminal 203 is connected to conductor S; terminal 201 to conductor 1, the tvvo terminals 202 to the conductor 2 and the conductor 21r to the conductor r. These conductors lead to the brushes 71, 72, 74, 73 and 91 respectively as sho-Wn in lFig. 7. Y

1t will be seen by comparing Figs. 0, 10 and 11 that when the contacter is depressed the ink numeral upon the transmitting sheet Will connect with terminal 21r with 'the tollovving terminals and produce the following amounts ot rotation in the movable switch element 30, 90.

i 201 1 2 204, 201, r02 7 3 204, 202 0 4 20s, 201 9 5 202 2 6 201, 202 s '7 204, 201 5 s 20s, 202, 201, 204 15 9 208, 204, 201 13 the type corresponding to the numeral at the place to which that numeral brings the Wheel and the proper numeral will thus be printed. 'li`he locations ot the type upon the Wheel is indicated in Fig. 11.

Should it be desired to use the Arabic numerals and nevertheless obtain a motion equal to the value ot .the transmitting Arabic l numeral, it may be accomplished by providl ing the element 89, 90 with a series ot radially projecting posts, 300, 301, 302, 303, 304i, 305, 306, 307, 308, 309, as shown in lFig. 1'1. These posts may serve as stops for plunger 320 supported bythe stationary bearing 321. The arrangement of the osts issuch as to bring the post correspon ing to the Arabic numeral ink character opposite to the plunger Whenever said ink character is 'contacted; and the height of said post above the zero level is equal "to the. numerical value of said numeral ink character. lllhe plunger may thus receive a dierential motion equal in value to the numeral character contacted.

To more fully` explain the function of plunger 320 and the stop pins 300 to 309 inclusive, let it be assumed that it is desired that the'mechanism should print the Arabic numerals and that the Vprii'itingY element should have a movement proportional to the 1,11*?, isa l value of the numeral printed. These nii-- merals or printing types will be formed on the plunger 320 or a part moving in directly proportional accordance with the movements thereof. As no means are shown lfor moving said plunger automatically it may be assumed that it is moved by hand. As the posts 301 to 309 are graduated as to height from 1 to 9 units, seriatim they will stop the pl'unver when moved leftward (Fig. 11) in nine different positions depending upon the post temporarily in line with the plunger. Consequently if the plunger be constituted a printing element, the type numerals thereon can be arranged successively, one next tothe other in normal order. Moreover mechanism connected thereto would thus be given an amount of movement corresponding to the numerical value of the numerical character.

A portion of the mechanism shown in this application is also shown in my ,copending application led January 10th, 1911, Serial No. 601,837, and also in my copending applicatiqn filed January 12th, 1911, Serial No. 602,228.
